EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 334,104, dated January 12, 1886.

Application filed May :6, 1885. Serial No. 166,692. (No model.)

T0 aZZ whom, it may concern:

Be it known that I, HEINRIOH F. BURMES- TER, a subject of the Emperor of Germany, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Extension- Tables, of which the following is a specification, reference being bad therein to the ac companying drawings.

My invention relates to certain improvements in extension-tables.

The object it has in view is to improve the construction of such tables, and especially the means employed for suspending the leaves in the table-frame when not in use.

To the accomplishment of the above the invention consists of certain novel devices and combination of devices, as will be described and claimed.

Reference will be made to the accompanying drawings, in which Figure 1 is a bottom plan View of the table extended with the leaves folded and in positions occupied when notin use. Fig. 2 is a longitudinal sectional View showing one leaf in use and the other folded in the frame. Fig. 3is also a longitudinal sectional view of a portion of the table with both leaves in position for use; Fig. 4, a cross-section on line 4 4. of Fig. 2, and Fig. 5, a eross-section on line 5 5 of Fig. 3. Fig. 6is a perspective view of the extension-frames of the table showing the leaves partly broken away,

Like letters refer to like parts in each view.

In the accompanying drawingslhave shown but two leaves, and the following description will be confined to such arrangement; but it will be apparent that more or less leaves may be used, if desired.

In the drawings,A A represent the two end sections or the table proper where there are no leaves in use. Each end section is supported upon two legs, B, and to the under face of each there are secured two strips, a a and a a, strips (6 a being secured to section A, and strips a a to section A. Upon the outer face of each strip a there is formed a suitable dovetail groove, into which a corresponding projection of a slide, 12, is inserted and adapted to move. Upon the inner face of each strip a there is formed a dovetail projection adapted to enter corresponding grooves of slides 0. Each slide a is provided upon its opposite face with adovetail projection arranged to be inserted into corresponding grooves formed in the outer faces of the slides 72, hereinbefore referred to.

By the arrangement as thus far described it will be seen that provision is made for the extension of the table, it being understood that any suitable stops are provided to prevent the different slides from separating. Secured to the upper face of each slide 0 is an iron, (I, bent outwardly and then downwardly, each of such irons being secured at its lower end to a cross-piece, O, to which the center leg, 0, of the table is secured. I have shown this arrangement; but I make no claim thereto, as it is the subject of a separate application filed by me, and therefore it will only be necessary to state herein that by means of the outward bends in these irons a space is formed between each and one of the slides c in which the slides 12 move and rest when the table is closed or being closed.

Upon the inner face of each. strip at, hereinbefore referred to,there is a groove, 6, (dotted lines Fig. 1,) into which the ends of a cross-bar, f, are inserted. Slides 6 are connected bya crossbar, g, which is connected by suitable strips, h, with cross-bar f, the distance between cross-bars f g being sufficient to aceomodate a leaf, D, therebetween. In bar f there is formed an L-shaped slot, k, the long arm of such slot extending about half the length of the bar. In the face of cross-bar g which is opposite to bar f asimilar slot, Z, is formed.

Secured to the under side of leaf D are two angle-irons, m, in the downwardly projectingarm of each of which is provided a pin, a, this arrangement being clearly shown in Fig. 2. The leaf D is formed of two pieces hinged together, and these angle-irons m are secured to the inner end of one piece of such leaf. Pins n are adapted to enter slots is Z, andwheu they rest in the short arms or branches of such slots the leaf, being folded, will restupon the strips h, before referred to as connecting crossbars f g. Vhen it is desired to use this leaf as a part of the table-surface, it is lifted until pins n are in line with the long branches of slots kl, when the pins are moved in such long branches towards the center of the table. When the ends of the slots are reached, the leafis unfolded and the end sections, A A,

5 .forced thereagainst if that is the only leaf to be used.

The slides a, hereinbefore referred to, are connected by two cross-bars, 0 0, situated on lower planes than the cross-barsfg, and connected by suitable strips, 1). Mounted upon cross-bar 0, and hinged thereto, is a bar, g, which when turned to rest upon bar 0 is on the same plane as the bar 9, hereinbefore referred to. This bar is hinged,as described,to render possible the closing of the table without the cross-bars coming in contact with each other. In one face of hinged bar q there is formed an L-shaped slot,s,' such slot being arranged,when the bar is resting upon bar 0, to be opposite to a similar slot, t, formed in the face of bar 9.

E represents the second leaf used, and is similar in construction to the one, D, before referred to.

Leaf E is provided with angle-irons v 12, one of which is placed near the side of the leaf, While the other is placed nearer the center of the same. In the arm of iron 1) there is mounted a pin, 11:, grooved at or aboutits ;0 center, as shown clearly in Fig. 2, this groove being adapted to accommodate atrack formed by strips 90, secured to bar q on the edges of the slot 8. Secured to theiron o is a pin, 11/, provided on its end with an enlarged head adapted to move in theslot of bar g, and being prevented from leaving the long arm of such slot by strips .1. Pin is longer than the one to, for the reason that the angle-iron to which it is secured is a greater distance from the slot which it has to enter.

There is an opening, y, Fig. 3, formed through bar g,said opening being provided to allow of the entrance of the pin w when the table is closed. It will be understood that this long pin w is provided to prevent the several parts from coming in contact with one another, and that when the parts of the table are pushed together it becomes necessary for this pin to move, and for this reason this opening is provided.

What I claim is- 1. In an extension-table, the combination, with the table and a folding leaf thereof provided with pins mounted in angleirons secured to the under side of the leaf. of a leafsupporting frame, the cross-bars of which are each provided with an L-shaped slot, as set forth.

2. In an extension-talole. the combination, with the table and a folding leaf thereof provided with pins mounted in angle-irons secured to the under side of the leaf, of a leafsupporting frame,the cross-bars of which are each provided with an L-shaped slot, and one cross-bar is hinged, as described.

3. In an extension-table, the combination, with the table and a folding leaf thereof provided with a long and short pin mounted in angle-irons secured to the under side,of a leafsupporting l'rame,the cross-bars of which are each provided with an L-shaped slot, and one of said cross-bars provided with an opening, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
